Vibration Diagnostics Testing

Vibration diagnostics are used to identify the root cause of noise and vibration problems in machinery.



In standard vibration diagnostics testing, techniques such as these are used to detect abnormal vibration characteristics.

  • Operating deflection shape (ODS) analysis
  • Spectral analysis
  • Order tracking
  • Joint time frequency (waterfall) analysis

These techniques are applicable to a broad range of vibration related problems such as:

  • Fatigue failures
  • Excessive noise & Resonance
  • Manufacturing process quality issues
  • Structural vibration
  • Abnormal wear
  • Floor vibration

Recent Diagnostics Testing

Recent vibration diagnostics applications include:

  • Failure investigation of a high-speed mixer
  • Detuning resonant vibration of a digester lid
  • Vibration reduction in a large centrifugal pump
  • Vacuum motor rotor dynamic resonance control
  • Vibration control in an x-ray machine

Why Noise and Vibration Testing?


Noise and vibration testing is extremely flexible in application and can be used in almost any field with a dynamic system. NV testing can be performed without causing alteration or damage to the structure while being sensitive to design, manufacture, and operation.

Below is a non-exhaustive list of examples:

  • Identify source of abnormal acoustic emission (example: LNG compressor oil and gas industry)
  • Identify source of abnormal vibration (example: ship to shore crane)
  • Identify source of abnormal wear (example: oven conveyor)
  • Ascertain cause of unexplained vibration (example: boiler feed pump)
  • Ascertain cause of unexplained noise (example: imagining equipment X-ray machine)
  • Improve quality of vibration (example: 3D printer)
  • Improve sound quality (example: kitchen blender)
  • Determine and reduce unexpected noise and vibration levels (example: dry dock crane)
  • Detect cavitation in pump (example: municipal water supply)
  • Characterize fluid instability (example: industrial mixer)
  • Verify presence of gear wear and provide direction to reduce wear (example: power tool power train)
  • Establish if dynamic concerns are related to assembly (example: generator end windings)
  • Describe motion of components that are designed to move in a particular path (example: oil and gas sifter equipment)
  • Explain how and why changes in design resulted in higher vibration or noise (example: centrifugal impeller)
  • Design optimization for oscillating equipment (example: personal grooming device)
